I can easily do 10K DPS. Looking back I would have chosen [CrtH] modifier instead of [Dmg], but its too late for that now.
If you want plasma weapons I suggest you use Romulan Plasma from the reputation system.
Also, stick to beam arrays instead of dual beam banks because of broadsiding.
Tactical consoles, keep them for boosting beam weapon energy types. Right now you have antiproton, use antiproton mag regulators. Keep universal consoles in science or engineering.
